Biopatterning for label-free detection [PDF]

open access: yesColloids and Surfaces B: Biointerfaces, 2010
We present a biopatterning technique suitable for applications which demand a high degree of surface cleanliness, such as immobilization of biological recognition elements onto label-free biosensors. In the case of label-free biosensing, the mechanism of signal transduction is based on surface bound matter, making them highly sensitive to surface ...

Geometric structure design of passive label-free microfluidic systems for biological micro-object separation

open access: yesMicrosystems & Nanoengineering, 2022
Passive and label-free microfluidic devices have no complex external accessories or detection-interfering label particles. These devices are now widely used in medical and bioresearch applications, including cell focusing and cell separation.

The Clean Label Concept: Novel Approaches in Gluten-Free Breadmaking

open access: yesApplied Sciences, 2021
The commonly used term of “clean label” refers to food products that do not contain additives (E numbers). Although there is not always a scientific reason for believing that additive-free products are healthier, clean label products are becoming more ...

Label‐free discrimination of extracellular vesicles from large lipoproteins

open access: yesJournal of Extracellular Vesicles, 2023
Extracellular vesicles (EVs) are increasingly gaining interest as biomarkers and therapeutics. Accurate sizing and quantification of EVs remain problematic, given their nanometre size range and small scattering cross‐sections.

Label-Free Monitoring of Diffusion in Microfluidics [PDF]

open access: yesMicromachines, 2017
Label-free, real-time detection of concentration gradients is demonstrated in a microfluidic H-filter, using an integrated photonic crystal slab sensor to monitor sample refractive index with spatial resolution. The recorded diffusion profiles reveal root-mean-square diffusion lengths for non-fluorescing and non-absorbing molecules, both small (glucose,

Label‐free characterization of an extracellular vesicle‐based therapeutic

open access: yesJournal of Extracellular Vesicles, 2021
Interest in mesenchymal stem cell derived extracellular vesicles (MSC‐EVs) as therapeutic agents has dramatically increased over the last decade. Current approaches to the characterization and quality control of EV‐based therapeutics include particle ...

Label-free receptor assays [PDF]

open access: yesDrug Discovery Today: Technologies, 2010
Label-free biosensors offer integrated, kinetic and multi-parametric measures of receptor biology and ligand pharmacology in whole cells. Being highly sensitive and pathway-unbiased, label-free receptor assays can be used to probe the systems cell biology including pleiotropic signaling of receptors, and to characterize the functional selectivity and ...

Metamaterial-based label-free optical biosensing

open access: yesCailiao gongcheng, 2021
Metamaterials have drawn extensive attention for their fine regulation of electromagnetic waves at subwavelength scales. They have abundant electromagnetic modes, and support highly confined and enhanced electromagnetic fields on the surface which are ...

High-throughput, nonperturbing quantification of lipid droplets with digital holographic microscopy

open access: yesJournal of Lipid Research, 2018
In vitro differentiating adipocytes are sensitive to liquid manipulations and have the tendency to float. Assessing adipocyte differentiation using current microscopy techniques involves cell staining and washing, while using flow cytometry involves cell

3D structured biochip for label free determinations at the point-of-need

open access: yesMicro and Nano Engineering, 2022
A novel optical label-free biosensing approach is introduced aiming to remove the current limitations of optical biosensors in their application of on-site food analysis.
